NAME
stty - (BSD) set the options for a terminalSYNOPSIS
/usr/local/heirloom/usr/ucb/stty [-a] [-g] [-h] [options]DESCRIPTION
Stty sets certain I/O options on the current terminal. With no argument, it reports the current settings of selected options; the -a flag causes it to report all options. With the -g flag, stty prints all settings in a form that can be passed to it again to restore the current settings. The -h flag prints a table of all control characters in addition to the output given with -a.Special option values recognized only if given as single argument are:
- all
- Print the normal output followed by a control character table.
- everything
- Same as -h.
- speed
- Print the speed rate.
- size
- Print the rows and columns of the terminal.
If either -g, speed or size are given, stty uses /dev/tty to get the terminal settings, otherwise, the standard output is used.
The option strings are selected from the following set; where an option is shown prefixed by `[-]', it can be negated as described in the text.

Control characters:
| intr c | set intr character to c. |
| quit c | set quit character to c. |
| erase c | set erase character to c. |
| kill c | set kill character to c. |
| eof c | set eof character to c. |
| eol c | set eol character to c. |

A control character may be either given as a literal character, or as `^c' for ASCII control characters CTRL-c; the special values `^-' and `undef' disable the control function. Multibyte characters cannot be used as control characters; trying to do so will result in the control character set to the first byte of the multibyte character sequence, which has the undesired effect of applying the control function to more characters than the one supplied.
